Olive oil is the best, but it lacks Omega-3 fatty acid. So you either need to supplement Omega-3 by taking tablets or capsules you buy from a nutrition store, or buy olive oil fortified with Omega-3, and of course eating plenty of fish is recommended too.

Also, peanuts, peanut oil, or anything made from peanuts have a trace amount of aflatoxin, a very potent carcinogen (cancer-inducing agent). There's no peanut oil that is completely free of this toxin.
